Collecting Mud

Look like Osmia bicornis (Red Mason Bee). They do nest in soil, but mainly wall cavitities, old wood etc. When seen in muddy locations, often collecting mud for construction/sealing of nest holes. These nests will be located elsewhere.

Do they nest in the soil? ;-)

Do they nest in soil?

I've never seen it personally, but the BWARS species description says they use "a variety of existing cavities, from burrows in the soil and dead wood ..."

Perhaps should have said "they CAN nest in soil".
